• In dry air, the adiabatic lapse rate is 9.8 °C/km (5.4 °F per 1,000 ft).
• The adiabatic lapse rate is the rate at which the temperature of a rising or falling air mass lowers or increases per distance of vertical displacement.
• The lapse rate, dry adiabatic lapse rate (DALR) and moist adiabatic lapse rate (MALR), are obtained.
• A rise from sea level into the upper regions of the atmosphere causes the temperature to decrease (see adiabatic lapse rate).
• If the air is at the saturation vapor pressure, then the rate at which temperature decreases with altitude is called the saturated adiabatic lapse rate.

• The difference between high temperatures is similar to the moist adiabatic lapse rate (3.3 degrees Fahrenheit per 1,000 ft), while the smaller difference between low temperatures is the result of frequent temperature inversions developing in the morning, especially during autumn.
• This temperature gradient is less than the value of the adiabatic lapse rate and hence cannot drive convection, which explains why the transfer of energy through this zone is by radiation instead of thermal convection.
• The water vapor condenses (forming clouds), and releases heat, which changes the lapse rate from the dry adiabatic lapse rate to the moist adiabatic lapse rate (5.5 °C per kilometer or [...] per 1000 feet).
• So cool air lying on top of warm air can be stable, as long as the temperature decrease with height is less than the adiabatic lapse rate; the dynamically important quantity is not the temperature, but the potential temperature—the temperature the air would have if it were brought adiabatically to a reference pressure.
